The company has said its GigaPower, which runs at speeds about 100 times faster than basic broadband, is available in “parts” of San Antonio, as well as “parts” of Cibolo, Leon Valley, Like Oak, Medina, New Braunfels, Schertz, Selma and unincorporated Bexar County.

The service is seen as direct competition to Google Fiber, which is expected to begin its rollout here in a year or so.

AT&T and Google appear poised to do battle in several cities with their fiber-optic services, while both also have staked out their own territory. Overall, experts say, the fight will benefit customers.

Reporters used crowd-sourcing Monday to try to better determine where GigaPower is available. Those who didn’t have access to the network appeared to far outnumber those who did. Others complained about poor customer service in trying to order the product.

Mayor Ivy Taylor praised the service in an AT&T news release.

“Having access to ultra-high speed internet service like AT&T GigaPower will have a huge impact on our economic future,” she said. “Super-fast access to data and cloud based services aren’t a ‘nice extra.’ They are now essential for anyone who wants to compete in the global economy.”

Councilman Ron Nirenberg also applauded the rollout but noted AT&T still has work to do.

“A great product at lightning speeds and faster to the market than anybody else is a welcome development in fiber for San Antonio,” Nirenberg said. “I would hope they iron out these service issues as quickly as possible so that we can experience the broadband revolution we’ve been talking so much about. I would expect with a company like AT&T, they can do that in short order.”

Monday apparently marked the day that customers could determine whether AT&T could provide GigaPower to their homes and businesses. Actual connections would be made in the coming days.

“We’ve seen a strong response this morning from customers already signing up to receive AT&T GigaPower,” a spokeswoman said in an email. “These customers can expect their installation to occur over the next few days. We’ll continue to expand availability throughout the San Antonio metro area throughout 2015 and beyond.”

Customers who sign up for the service will get a three-year price guarantee, along with waived equipment, installation and activation fees, according to an AT&T news release.

The telecom giant will charge $70 per month for gigabit Internet — about the same cost as Google Fiber has charged in its markets — $120 monthly for Internet and TV, and $150 per month for Internet, TV and telephone.

Renee Flores, regional vice president for external and legislative affairs, declined to say how many customers would have access to GigaPower on Monday — or by the end of the year — but issued a statement saying her company is “excited” about the launch.

“Launching today is just one more milestone on the path to providing these blazing fast speeds in the San Antonio area,” Flores said. “We are excited about keeping up that pace as we expand and enhance the AT&T GigaPower network to more locations. Champion speeds for a championship city!”
